My B-I-L asked me if I knew of any issues   with these,  as   he suspects something may be developing, although I am unsure of exactly what symptoms are showing.

 I promised to enquire here, although I don't know if these are, or were sold in the USA, but there are other nationalities who  frequent this Forum too, and may  have an answer also.

I understand it is an 04 build.

Thanks
